I feel the top part of the UI takes a little too much space from the oncoming road. The damage indicator could be smaller, the coin and points counters could also be smaller. (Maybe replace icon with text?)
Tilt to steer can be hard while on the move. An alternative such as touch on each side to steer, with forward tilt to boost (for non multitouch phones) would be nice to have.
Points = cash? A certain amount of the points you make should be cash-points as well. Or there could be coins with higher values on the road?
I feel this because I feel the initial curve is "abit" to high, and I think to be able to hook more players, you should be able to purchase an upgrade pretty fast in the game.
Anyhow, I have just played this game for a few minutes, and it's great! Just my 2 cents. No bugs til now at least (nexus 4)
